Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559176, here are decompositions:

83 + 31559093 = 31559176
107 + 31559069 = 31559176
149 + 31559027 = 31559176
179 + 31558997 = 31559176
293 + 31558883 = 31559176
317 + 31558859 = 31559176
353 + 31558823 = 31559176
443 + 31558733 = 31559176

Showing the first eight; more decompositions exist.
